DERRIcK-NET FOR STACKING.

SPECIFICATION forming part of Letters Patent No. 264,915, dated September 26, 1882,

Application tiled July 1, 1882.

To all whom it may concern:

Be it known that l, GEORGE WILKINSON, a citizen of the United States, residing at Acampo, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Derrick-Nets for Stacking; and I do hereby declare the following to be a full, clear, and exact description of the invention, such Vas will enable others Askilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures --of reference marked thereon, which form a part of this specication.

My invention relates' to certain improvements in that class of agricultural implements extensivelyr used in the State of California as false bottoms ol" header-wagon beds, upon which false bottoms are deposited the cut-grain straw, which .is poured thereon from the conveyers or drapers of the spouts ot' heading-machines in the harvest-field. These false bottoms are termed amon gl'armers derriclr-nets.77

My invention consists iu the combination of the two sections ofthe net in a peculiar manner, both sections being of equal size, by means ot' a hinge at the one end ot' the two inside holding-bars and by a spring-latch at the other ends thereof 5 .also, in securing the bottoms of canvas, rope, or other suitable material to the holdingbars by iron straps bolted to said holdingbars, all as will be more fully described hereinafter.

Referring to the accompun ying drawings, Figure l is a perspective of a complete net with sections united. Fig. 2 is a view of the inner bars, showing the hinge and spring-latch by which they are united. Fig.3 is a vertical section of my invention. Fig. 4 is a view of one of the bars with iron strapv bolted thereto.

A A are the sections of my improved net, having outside bars, B B, and inside bars composed of bar C, having shorter bar O bolted thereto, with spring-latch c at its head, and of bar D, having short bar D' bolted thereto, with spring-latch eye d at its foot. The canvas or rope bottoms of the sections are attached to the bottoms of the bars by iron straps A slip or pulling cord, E, connects with spring-latch c, at its rear,'through a circular orifice the entire length of bar C', and is (No model.)

or" suiicient length to be within easy reach of the operator.l

The `method of using my improved net is as follows: It is spread in the bottom of the bed of the header-wagon, both sections of course being united, as hereinbefore stated. As soon as a sufficient load of grain-straw is received from the heading-machine the ropes usually attached to bars B B, as shown in Fig. 1, and having rings or eyes at their extremities, are by such rings connected tothe hooks of blocks ofthe raising-tackles. The load is then raised to and over the point of discharge. The cord E is pulled bythe operator, releasing the latch c from its eye d, whereupon the two sections of the net fly outward from the inner points ot' bars O and D', the lower inner-points of said bars G and D being of course held together by tbeirhinge, as hereinbefore shown. The load then discharges, after which the two sections of the net are brought together againv and latched, and the operation, as previously described, is repeated. rIheiron straps e e e e insure greath strength, and also prevent chating of the canvas or rope bottoms of the net. For carriage, both sections can be rolled up compaetly and into a small compass.

I am aware that similar nets with hinge at one end ot' inside bars and catch or latch at the other have long been in use.- Hence What I claim as new, and desire to secure by Letters Patent, is

1. A derricknet for stacking purposes, com posed of the section A, having an outside bar. B, and an inside bar, O, having attached to it a bar, O, carrying spring-latch c at its head, and cord E, and of the section A, having an outside bar, B, and an inside bar, D, having attached to it a bar, D', earryin g spring-latch eye d at its foot, the said sections A A being permanently secured together at lower inside corners by hinge at end of bars O and D and atv upper ends by latch c and its eye di, located as shown, said latch c having a trip-cord7 E, attached to it and extending therefrom down through circular hole in bar O to within easy reach of the operator, all arranged and oper- IOO and a cord, E, extending from said latch down through a circular hole in bar C', and extending beyond it, so as to be within reach of the operator, all for the purposes substantially as herein described.

3. The combination o'f the bar D with the bar D', having at its foot spring-latch eye Z to receive spring-latch c, all substantially for the purposes herein described and set forth.

4. The combination, with bars B B, (Land I D, of iron straps bolted thereio and securing canvas or rope netting of sections A A, as and l'or the purposes herein described and set forth.

Intestimonywhereof I affix my signature in presence of two Witnesses.

GEORGE WILKINSON.
